Question

If a wave has a wavelength of 9 meters and a period of 0.006, what is the velocity of the wave ?

Answer 1

V = wave / time
V = 9 / .006
$v = {1500ms}^{ - 1}$

Answer 2

Answer:

1500 m/s  

Step-by-step explanation:

The formula for the period T of a wave is

  T = 1/f      Invert each side

(1) f = 1/T

The formula relating frequency f and wavelength λ is

(2) fλ = v     Substitute (1) into (2)

     v = λ/T

Data:

λ = 9 m; T = 0.006 s

Calculations:

v = 9/0.006

v = 1500 m/s
